I believe this piece consists of three main musical elements. One is what I call "resonance," a material that serves as an afterglow rather than a melody or accompaniment, specifically the right-hand triplet figure in measures 1-2. This element appears throughout the piece. When performing this "afterglow," never produce a loud sound; instead, play it to create a blurred, dreamlike atmosphere.

Next is the melody line, followed by the accompaniment figure. A section where the melody line and accompaniment figure are easily confused is from measure 32 onwards. In the right-hand notes, those with stems pointing upwards constitute the melody line, while the others are part of the accompaniment. Please differentiate them by keeping the volume of the accompaniment figure subdued and bringing out the melody line clearly.

In measures 9-10, the half notes B and A appearing in the left hand form the melody line. This descending second melody line appears throughout the piece. Here too, distinguish between the melody line and the resonance (afterglow) through differences in tone quality and volume.
